BREECH-.LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 434,062, dated August 12, 1890.

Application iiled December 80, 1889- Berill No. 335,467. (No model.) A

.To all whom it may concern:

Beit known that I, LEWIS L. HEPEURN, of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Magazine- Guns, of which the followingis a specification.

view of that portion of the gun which contains the operative mechanism with the side plate shown detached.. Fig. 2 is a side view of the same, showing thebreech open and the carrier raised. Figs. 3, 4, .5, vand 6 are views of portions detached; and Fig. 7 is a trans- 'vese vertical section on the line a: of Fig.

2, as it would appear' with the side plate B secured in place. Fig. 8 is similar to Fig. 1,

except that a portion of the stock and a portion ofthe carrier are broken away to show the working parts. Fig. 9 is a horizontal section of part of the frame on line z e of Fig. 7,

showing the method of forming and mounting the ejector-spring.

This invention is an improvement upon the lire-arm shown in the Letters Patent granted to A. Burgess, November 19, 1876, No. 210,091, and that of my prior patent, No. 400,67 9; and its object is to simplify and render more efficient the mechanism thereof, with especial reference to the use of what are known as No 22 cartridges; but many of these improvements will be found Valuable in guns of a larger caliber. My present gun differs from that of this Burgess patent in having its opening forl ejection of the cartridge-shells 'at the side instead of the top of the breechframe, and in having its breech-bolt sustained more firmly by its locking-lever', and in various other details of constructomas hereinafter described and claimed, and it dilers from the gun of my said former patent iu .having the breech-block locked by a lever instead of the sliding bolt D of that patent,

n and in providing a superior form of cartridgecarrier and superior means of operatingand controlling the same, and also in various other details of construction, as hereinafter described and claimed.

A is the frame of the arm, which is formed of a solid block of metal with the recess for the breech mechanism chambere into one side of the same. The barrel C is solidly attached Ito the front end of this frame, so asto open into the upper. part of the-recess in the latter. The magazine also opens into this recess below the barrel, being placed underneath and parallel to the latter, as in my said former patent. 'lo the rear part of the trame the stock of the gun is attached. The hammer H is. pivoted in the 'frame in line with the reciprocating breech-block F, so that the backward movement of the latter will set the hammer ready for iring. This breech- .block comes out flush with the upper part bearing and sliding upon the inner correspending dat surface of the traine. Underneath the breech-block the recess in the which forms the guidewa on which the breech-block rests and sli es on that side. The outer face of plate B, when in place, is

F, and the withdrawal of the breech-block leaves an opening in the side of the frame through which the cartridge-shell is ejected after the gun is fired. One object of this general 4construction to eject the cartridge sidewise from the frame is to avoid the liability' of parts of the shell being throwniupward and out of the top of the frame into the face ,of the person firing the gun. The special purpose of the construction is to give the breech-block a much broader and more extensive frictlonal bearing-surface on top than was possible with the former construction, where the frame was operi on top tor the ejection of the. cartridge, and 'the breech-block was supported and guided by small ways and grooves on 'its vertical sides.

L L is the lever which is used to operate the breech-block to and fro in the frame of the gun, so as to close and open the breech by means of a mortise fn? in the lower side of the breech-block, into which it enters as its i. upper end swings upward from the locking of the frame, and has its flat upper surface I side of the frame is closed by a fiat plate B,

iiush with the outer side of the breech-block ICO l being dispensed with?.

positioinand it also locks the breech-block in position for tiring, by nicans of a segmental surface 'n' on the latter, against which the end ot the lever braces when the breech-block is closed, like that of Burgess, the locking-bolt D for that purpose of my said former patent In order to enable the `lever L to assume a position more nearly in a direct line with the guideways of the breech-block, to form a more edective lockingbrace to hold the latter closed during the discharge of the gnu, the segmental surface n' on the breech-block, against which the lever takes its bearing to lock the breech, is notlocated on or in the breech-block, as heretofore,

but entirely below the bore of the gun, upon a downwardly-proj ectin g abn tment n2, extending below its lower surface. By this mea-ns1 am not only able to bring the lever L ,more nearly to a parallel position with relation to the longitudinal axis of the breech-block, but v also to pivot itunderneath the carrier and in frontfof the pivot h of thelatter, so as to enable it to operate thereon, its-hereinafter described,and at the same time serve as an eicient breech-locking brace, without unduly lengthening the frame or working parts of the breech mechanism. Just above and behind the abutment n2, and toward lthe stock4 of the gun, I provide a mortise a5 in the lower side of the breech-bolt F, as clearly shown in Fig.

, 3, into which the upper end of the lever L' enters as' it leaves the segmental surface fn, and by engaging with the walls of this mortise it withdraws the breech-block and again brings it'up to the barrel on the return-movement of the lever. The breadth of this mortise n shouldbe so proportioned as to allow the lever L to perform its functions in operating the carrier, as hereinafter described.

. The lever L L is pivoted to the frame at l,

' and has a shoulder I. concentric with its pivot,

which takes a bearing against a correspondingly-formed part of .the frame when the breech-block is closed, to assist the pivot in resisting the strain of the discharge upon it. This construction of these several parts is superior to that of former constructions in this: That the tendency of the breech-bolt to force back the leverL L and be opened by y the force of the discharge in the formcrguns was very great, because the comparatively slight breadth-of the bearing-surface ofthe guides in which it ran allowed too great strain to be thrown upon the lever L', and it was practica'lly impossible to materiallyr increase the breadth of bearing-surface of these guides,

' because the frame was open at the top to allow the shell to be ejected. Itis found, however, thatwith the frame open at the side for the ejection of the shells the extent of the frictional--s-urface of the frame above it, againstwnieh the breech-bolt can be made to hug by the locking-lever L', is so'great that the strainupon the lever from thev explosion of the cartridge is greatly relieved, and it is, therefore,practicable to employ the leverfor locking the breech block, thereby greatly simplifyin g the breech-n1echanisin of the gun. It is evident that for any given dimensions of frame this advantage will always be had by the present construction.

Thenext improvement Vis in the construction of the breech-bolt F with a shoulder n upon the abutment n2, which extends down past the floor of thepcarrier E when thev latter is in its elevated position opposite'to the mouth ot the magazine ot the arm, and is adapted to receive the cart-ridge to' be delivered upon the carrier against it, and conduct the cartridge upon the carrier without shock or jar, which might be liable to explode the cartridge. The carrier E is pivoted at h and must. be allowed to rise up with the cartridge and remain in that raised position while the breech-bolt moves forward and passes almost or quite through its length to force the cartridge forward into the breech-chamber, because this gun is intended to use very short as well as longer cartridges. The carrier is therefore cut away on one side to allow the dependingabutlnent n, with its shoulder u of the breech-block, to pass by it and-come i gun by the breech-block, while the eapaxsity of the magazine and gun to receive and manipulate long cartridges in transferring them from the magazine to the barrel is not interfered with.' Heretofore when any depending portion of the breech-block has been employed to conduct the cartridge upon the carrier it-` has not been possible `to have the latter rise up and hold the cartridge in placev4 while the breech-block with such depending attached portion was movingthrou-gh it.

Just above the shoulder n on the abutment ln? of the breech-bolt I provide the bolt on its forward end with a projection i, having a bevel upon ,its u-pper edge, Fig. 3, which extends down below the bottom of the floor of the elevated carrier on which the cartridge rests, traversing along past the cut-away part of the carrier with -tl1`e depending shoulder n, as above described. The beveled projection 1' serves as the breech-block advances Ito lift;

-the rear end of the cartridge off from the inclined carrier-bed and raise the axisof the cartridge substantially into line with the bore of the barrel, `thus causing the cartridge, es-

IIO

pecially if a short one, to be pushed into the tically up and down in guideways to bring short cartridges into line with the barrel. 0n theside of the carrier next to the shell- 'ejection openingl'provide it with a thin wall or lip a, extending up high enough to prevent the shell from escaping by passing over the shell-ejection openingwhen the carrier is raised tothe level of thc barrel. On its extreme front end this wall or lip ct is cut away to permit the cartridges to be fed over it into the magazine when the carrier is down in the position shown in Fig. l. In the side plate B, I provide a gat-e or door, which swings edgewise downward, as hereinafter described, iu a recess in thc'inncr face of theplate, thus avoiding interference with the lip or wall o| of the carrier. lly these constructions of thc several parts I am enabled to retain the cartridges upon the carrier and prevent their escapo in au effective manner, while not impairing the capacity of the arm for reloading the magazine.

By the new arrangement of the lever L L',

I am enabled to carry its pivot Z so far back toward the pivot h of the carrier as to dispense with the eccentric on it which was used in combination with the inclined lower sur- Vof the carrier, raising the carrier at-its free end suliciently to arrest the succeeding cartridge to the one being conducted onto the carrior by the retiring breech-block at the opening into the magazine. The magazineis coustructcd under the barrel in the usual manner, and has aspiral spring to push out the col-umu of cartridges as fast as they are removed by the carrier. trically-moving shoulder Z2 on the lever, in

combination with the bevel e2 upon the car` rier, to raise the latteigxas described, is necessary, in order to permit the concentric shoulder l ef the lever L L te take its bearing supporting the lever in. the corresponding recess of the frame, as before described, because this shoulder Z" partly occupies the space of the eecentric before used, this bearing-shoulder t being practically indispensable to the lever when used in locking the breech-bolt, as well as moving it. l

. In practice it is found veryeouvenient, and with guns using small cartridges quite necessary, to be able to readily and quickly get at and clean the breech mechanism of the gun. The shortness of the shells of small cartridges prcven ts the sealin g of the space i-n the breechchamber around the shell sc eiicetivelyas with larger cartridges, and therefore allows the breech mechanism to foul more easily. To get at the breech mechanism readily and quickly, I make the cheek-piece or side plate B of the frame so that it can be removed by hand and without the use of a screw-driver or other tool. Furthermore, as it carries the race or guide way on which the breech-block l? runs or bears on one side, I provide one or more shoulders s s2 on or attached to the frame,

which project underneath it and' support it This employment of the concenaccurately in position. The cheek-piece can thus be removed and replaced without impairing its efficiency in supporting the breechblock race. As shown iu Figs. 1 and 4, the front end of this plate 13 is provided with a small projection or lip p, which engages in a correspondiugly-shaped under-cut or recess formed in the frame,aud it is also provided with a screw or sinall bolt I, formed with a head projectii'ig'outside of plate B and provided with milling or projections thereon, suitable to be grasped and turned by the thumb and finger.. This bolt has vits body made of such a size that it will slide freely through its holo in plate B; and near its opposite end, f

which is provided with a screw-tl1read to engage in a screw-hole in the opposite wall'of the receiver, it has a projection or collar e attached firmly to it, of such a size as will prevent the boltfrom being drawn entirely out' of its-hole in cheek-piece B. Insteadof being in the form of a collar, as shown, this prjec' tion may be a pin put through the bolt, or of other well-known form, that being immaterial so long as it serves to prevent the bolt from being removed from the plate.

By allowing the bolt to slide for a limited distance outward through the cheek-piece B before Yit is arrested by projection e it b9- comes a more eicient handle to pull the plate out of its recess'in the frame after the bolt is uus'crewed, and the rear end of the plate coming out firstthe lip p is disengaged by drawing the platebackward. As, an aid to the introduction of the plate or cheek-piece B to exactly its proper position, I provide the projections s s* upon the frame above it to co-operatewith projections s4 s2 below it, and I prefer to employ them, as shown; but they may be omitted, if desired. Instead of the lip 1), the front end of plate l may be cut on a bevel and made to engage in a. correspondingly-shapcd seat in the frame.

'lhe carrier is operated by tho arm L of lever L L' by means of a detent or springlatch o, set so as to move transversely yin a recess er slet ymeut in the carrier E, as shown in liigs. 1, 2,3, and4, and have the dog or hook of the detcnt project beyond the face of the carrier and engage with lever L' at the proper time to move the carrier, as hereinafter de scribed. Instead, however, of pivoting the detent loosely in the carrier, as heretofore, and providing it with a rear shoulder for the arm L to strike against, to set its hook or dog in position. to engage with the 'arm on its return-movement, I now construct it so as to be set in that position by a spring, which presses it against the face of the arm as the latter passes by it. For convenience ofl construction the recess containing the detent extends back to and around the carrier-pivot h. The rear end of the detent o is provided with a hole'itting loosely over this pivot as it lies in its recess, as shown in Figs. 3 and 5. The other end of the recess is undercut, and the beveled end et the datent extends into this head. This extractor t is made wit-h a solid responding recess formed in the-side wall of 30 angled the same as before, I provide a curved but is secured to the breech-bolt FI in a novel manner. As' shown in Fig. 6, a groove is milled or cut in the top of the bolt forabout half its length at apoint just iu line with the right-hand wall ofthechaniber, or nearly'so, and of suflicient depth to permit the extractor` tto be set therein and have its hook come opposite the right-hand side of the cartridgeshank of the proper size to fit snugly in the recess in position to hold the spring-hook end of the extractor properly to engage with the i cartridge-head by the action of the opposite solid walls of the recess upon the shank. This is due to the factthat the walls of the recess bear snugly upon the shank` of the extractor on the same side as its hook, and'on the opposite side thereof for a certain distance from the heel of the shank, and the spring part of 'the extractor is thinned down from thenceto-- ward its hook end, so as to allow the propermovement of the spring end in the groove for its hook to'spring over the cartridge-head. The solid walls of the breech-bolt thus take all the strain brought upon the shank of the extractor, and there are no holding-screws to come loose or wear out. On one side of the shank is a projection rra-which fits in a corthe long recess, as shown, and which serves to lock the extractor in place and prevent it from being pulled endwise out of its seat when extracting the shell. The extractor thus made is simply set in the recess Without other fastening, it being prevented from rising b y the top wall of the frame when the breech-bolt is in position, but being free to be lifted out when the bolt is detached. By this construction I avoid the use of any pin or screw, and ani enabled to remove the extractor, whenever desired, by the thnmb'and finger and without the use of a tool.

The form of the spring-ejector claimed in my said former patent is improved especially to adapt it for short cartridge-shells and cause it to throw them ont more certainly, although it is better for longer ones also. In front of the shoulder r1",which is made rightnose 83, which extends outward in front of the shoulder and reaches around thecartridgehead and strikes the shell between the head and open end of the same on its side. This is eected by making the notch in the ejector between the shoulder' 'il and the nose 3 deep enough to allow the head of the cartridge'to enter it as the ejector springs forward, and thus allow the force of blow of the ejector uponthe shell to be delivered first by the nose 'L3 before it strikes .the side of the head of the cartridge. The head of the cartridge being at the same time held by the extractorhook t, the backward movement of the breechboltbrings the opposite side of the cartridgehead against the shoulder 7? and tends to throw the shell forward toward the open end of the barrel aswell as outward, (giving it a 1 rotary motion in ahorizon tal plane,) and butI for the nose 'i3 of the ejector the shell would frequently strike the end of the barrel and certainty.

In order to prevent the gun from being fired before the breech-block is locked by the lever L, I. provide a guard-spring 1, which bears upon the trigger 2 when in its normal position below the pivot 3, on which the latter is hung. The scar or nose piece 4 of the trigger is hung upon-the same pivot,'so that the trigger '2 has a slight movement of that part to allow the end of spring 1 to pass behind it. Onspring 1 is fixed a stud 5, which projects downward t-h'rough the frame into' the path of arm L of lever L L', so that during the last part of 'its movement when it is locking the breeclrit shall come in contact with this stud atl its otherend and lift the free end of spring l from behind the trigger, allowing t-he latter to be operated to fire the gun. The frictional bearing of the end of part L of the lever against the breechbolt is very useful in keeping the part L of the lever pressed up against the stud 5, so that the trigger may remain unlocked and ready for firing, as described', such frictional bearing being so far from the pivot Z of the lever. To aid in holding the lever L L in this closed position, I have provided a spring 6, the nose of which enters the notch 7 on the periphery of the hub of the lever when the latter is closed. The nose of the spring is rounded and springs out of the notch when the lever L is carried forward to unlock the breech.

It is evident that by providing the breechbolt with the segmental locking-surface n', and pivoting the lever L underneath the carrier and between the pivot of the latter and its free end I am enabled to allow the carrier to remain down opposite the magazine during the backward motion of the lever, which unlocks and withdraws the breech-block andcond nets thecartridge upon thc carrier, and on the return-movementof the lever to both raise and depress the carrier while the breech-block is moving forward and being locked by the lever,

roo

and that thisl double movement of the carrier during one movement of the lever is due to the position of their pivots to each other, as described, and of the segmental locking-surface n. generally of the movements'of these parts, but

Furthermore, not only is this true.

the location of the segmental locking-surface n' on an abutment depending below the line of bore of the barrel gives to the lever L' a greater amount of sweep and' movement in -which to actuate and hold up the carrier and deliver' the cartridge to the barrel before the bieeclrblock is locked, and thereby increases the certainty of handling the cartridge, as well as the locking-powerof. the lever against segmental surface n.

By the above-.described improvements l am enabled to produce a gun of superior breech mechanism, which handles the cartridges so certainly and perfect-ly in transferring them yfrom the magazine to the barrel and ejects the shells so certainly that small cartridges like No. 22-can be used with it as well as -larger ones. lt will also automatically handle and take care of cartridges of different block F, provided with the segmental surface lengths as Well as those of the same length, even where the former are mixed'indiscriininately in the magazine. l
